Reset Switching Threshold
The internally set reset threshold is 4.65 V. When using the TLE 4470 G (PG-DSO-20)
this threshold can be adjusted to 3.5 V <
divider to pin RADJ. If this pin is not needed, it can be left open or even better connected
to GND.

The reset output pin is internally connected to the stand-by output Q1 via a 30 k pull-up
resistor. The reset LOW signal at pin RQ is guaranteed down to an output voltage
of 1 V typical.
